My invention relates to fountain pens of the self filling type in which a sack is used in filling the pen.

. The ob'ect of my invention is to provide Q a self filling pen having the following features of novelty and utility.

First, a pen which may be made at a. low cost, constructed with a soft rubber collapsable tube in open communication with a glass w bottle which may be filled to serve as a part of the reservoir with the ink therein exposed to View. 7

Second, a pen having telescoping metal tubes, the outer one being exposed to View He thru a translucent or transparent outer casing, and plated with gold, silver, or other colored material, or used without the outer casing, and exposed directly to the. atmosphere for a portion of its length.

Third, a pen which may be madev without the bottle feature, by substituting a rubber sack of the usual construction for the rubber tube shown in the drawing herewith submitted. j

Fourth, a pen having the above features and constructed so that the reservoir portions of the pen may be easily separated from the casing portion without being disassembled as a reservoir unit.

.Referring to the drawing which forms a part of this specification; I

Fig. 1 is a longitudinal sectional View of a fountain pen embodying my invention.

Fig. 2 is a cross sectional view taken on line 2-2 of Figure-1, shown on an enlarged scale.

Fig. 3 is a perspective view of the glass bottle'portion of the reservoir.

Fig. 4 is a view of the transparent end cap which covers the bottle portion.

Fig. 5 is an end view of the transparent end cap shown on an enlarged scale.

A- indicates the pen section, and B- a feed plug fitted therein, and provided with a small tube C, the open adjacent end of whichis in open communication with the feedduct B by asmall open passage C- formed in the feed-plug.

The tube 0- extends thru the reservoir D-' to a point adjacent the rear end thereof, as shown.

.The pen section A .is reduced in diameter at E- to provide asurface over which an ,in-

Her tube F fits in frictional engagement and 5 is readily removable therefrom. This tube is made from thin sheet metal by drawing dies, and presents a true smooth cylindrical outer surface over which the outer tube G- fits in closeair tight sliding'relation. The gm outer tube is made in the same manner as the inner tube, and its outer surface may be plated with any desired rich colored metal such as gold, or silver, or colored lac or enamel.

. This outer tube G- may be made thick enough to serve as an outer casing, if desired, but I prefer to use a separate outer casing such as amber colored bakelite, or light colored cellulose material that is transparent,

and to connect it to the pen section by a friction joint asillustrated at H the casing portion being indicated by H. The outer casing H is separated from the outer tube G by a very small space to prevent friction between the tube and inner wall of the casing. T indicates a transparent or translucent end cap which is threaded to connect with the outer casingat I and is connected to the outer tube G at the point J, so that the outer tube G is movable with the end cap in the'filling operation of the reservoir K. The end cap is provided with a hole I"' to serve as an air passage.

. The inner end of the pen section is reduced in diameter to receive the open end of the,

soft rubber tube or sack L which is fastened thereto in the usual manner, and the opposite end of the .tube L is connected to the open end of a glass bottle or tube M by the use no of shellac or other suitable means.

In case -a pen is made without the bottle M the tube L is made longer to correspond with the length" of the bottle. and its end closed, or in other words, a sack is substituted for the tube shown. and this event the cap I may be dispensed with if desired,

and the tlescopingtubes of metal and the out er casing tube of translucent material may be increased in length, to cover the sack, and the outer tube G- may beallowed to'extend beyond the casin H to permit it to be grasped by the gers during the filling operation.

It will be obvious to those skilled in the .art to which this invention pertains, that within the pen section and within the ru ber sack and bottle.

The pen is filled as follows:

the surface of the ink in the ink-receptacle, then unscrew the cap I from the casing H-' and withdraw the cap and outer tube G- which is connected thereto, partway from the outer casing H'-, then cover the hole I- in the cap with a finger and reciprocate the cap slowly three or four times, and after the last outer stroke, remove the finger from the hole connected thereto, .thru the hole I- and trapped therein by covering the said hole with the finger, and then compressed as the tube is forced inwardly, which acts to deflate the rubber sack L- and force the air from the reservoir 'thru the air tube C, and on the outward stroke the air is rarefied which causes the sack to expand and draw ink into 7 the reservoir and be trapped therein. The
